+# Prometheus Druid Exporter
+
+A Prometheus exporter for [Druid](https://druid.apache.org/) metrics.
+
+Installs the [Druid Exporter](https://github.com/opstree/druid-exporter) for [Prometheus](https://prometheus.io/).
+
+Some of the metrics collections are:-
+- Druid's health metrics
+- Druid's datasource metrics
+- Druid's segment metrics
+- Druid's supervisor metrics
+- Druid's tasks metrics
+- Druid's components metrics like:- broker, historical, ingestion(kafka), coordinator, sys
+
+## Get Repo Info
+
+```console
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+helm repo update
+```
+
+_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Install Chart
+
+```console
+# Helm 3
+$ helm install [RELEASE_NAME] prometheus-community/prometheus-druid-exporter
+
+# Helm 2
+$ helm install --name [RELEASE_NAME] prometheus-community/prometheus-druid-exporter
+```
+
+_See [configuration](#configuration) below._
+
+_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
+
+## Uninstall Chart
+
+```console
+# Helm 3
+$ helm uninstall [RELEASE_NAME]
+
+# Helm 2
+# helm delete --purge [RELEASE_NAME]
+```
+
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
+
+## Upgrading Chart
+
+```console
+# Helm 3 or 2
+$ helm upgrade [RELEASE_NAME] [CHART] --install
+```
+
+_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
+
+## Configuration
+
+See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](https://github.com/prometheus-community/helm-charts/blob/main/charts/prometheus-druid-exporter/values.yaml), or run these configuration commands:
+
+```console
+# Helm 2
+$ helm inspect values prometheus-community/prometheus-druid-exporter
+
+# Helm 3
+$ helm show values prometheus-community/prometheus-druid-exporter
+```
+
+### Druid Server Connection
+
+To use this chart, ensure that `druidURL` is populated with valid Druid URL. Basically this is the URL of druid router or coordinator service.
+
+An example could be:-
+
+```console
+http://druid.opstreelabs.in
+```
+
+### Service Monitor
+
+The chart comes with a ServiceMonitor for use with the [kube-pometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack). If you're not using the Prometheus Operator, you can disable the ServiceMonitor by setting `serviceMonitor.enabled` to `false` and instead populate the `podAnnotations` as below:
+
+```yaml
+podAnnotations:
+  prometheus.io/scrape: "true"
+  prometheus.io/port: "metrics"
+```
